Product Description
Product Overview

This custom non-standard aluminum alloy locating block is manufactured by high-precision CNC milling. It retains the original machined surface without extra surface treatment, featuring stepped profiles, large positioning bore and mounting holes. It is designed for positioning, clamping and connection of automation fixtures and mechanical assemblies. Integrated one-clamping machining ensures excellent hole coaxiality and dimensional consistency. We support OEM & ODM customization from prototype sampling to mass production according to your drawings or samples.

    I compared several companies, but I still consider Chenrong products to be the best—whether in terms of service quality or after-sales support.

    These replaced a bent factory support on our CNC router's Z-axis. Machining quality is genuinely good the flange face is perpendicular to the bore, no runout issues once installed. Weight savings over the original steel post is noticeable.
